摘要
The fields of engineering, architecture and urbanism ought to ponder on constructive changes to be employed in the environment. Environmental vulnerability usually reaches sites with greater abundance of water resources that are exposed to contaminable factors, which usually become residential expansion areas, and often extrapolate city boundaries. The general objective of this study is to assess physical characteristics of the subbasins of the Curtume and Agua Preta streams, located in the Paraiba do Sul watershed in the municipality of Pindamonhangaba, in the state of Sao Paulo （SP）, Brazil. The current situation regarding this environment, based on soil type and morphometric and physiographic attributes, is specifically sought to be identified. The results show the morphological and physiographic relationships with the hydrological data that determine the natural pattern of the site, associated with anthropic actions that characterize potentialities and vulnerabilities of the area, thus determining environmental dynamics. The results demonstrate that urban sprawl and residential constructions in subbasin conservation areas should occur in a planned and strategic manner, without advancing to water conservation areas.
